Method Details

containsKey

public boolean containsKey(double key)

Description copied from interface: Double2ShortFunction

Returns true if this function contains a mapping for the specified key.

Note that for some kind of functions (e.g., hashes) this method will always return true. In particular, this default implementation always returns true.

Specified by:

containsKey in interface Double2ShortFunction

Parameters:

key - the key.

Returns:

true if this function associates a value to key.

See Also:

• Function.containsKey(Object)

Specified by:

containsKey in interface Double2ShortFunction

Specified by:

containsKey in interface Function<Double,Short>

Parameters:

key - the key.

Returns:

true if this function associates a value to key.

get

public short get(double key)

Description copied from interface: Double2ShortFunction

Returns the value to which the given key is mapped.

Specified by:

get in interface Double2ShortFunction

Parameters:

key - the key.

Returns:

the corresponding value, or the default return value if no value was present for the given key.

getOrDefault

public short getOrDefault(double key,
 short defaultValue)

Description copied from interface: Double2ShortFunction

Returns the value associated by this function to the specified key, or give the specified value if not present.

Specified by:

getOrDefault in interface Double2ShortFunction

Parameters:

key - the key.

defaultValue - the value to return if not present.

Returns:

the corresponding value, or defaultValue if no value was present for the given key.
